| pseudomonas arsenicoxydans sp nov., an arsenite-oxidizing strain isolated from the atacama desert. | a gram-negative, arsenite-oxidizing bacterial strain, designated vc-1, was isolated from sediment samples from the camarones valley in the atacama desert, chile. strain vc-1 was strictly aerobic, oxidase and catalase positive, rod shaped, of about 5.5 microm in length and 0.5-1.0 microm in diameter. it was motile by means of multiple polar flagella. the phylogenetic reconstruction of the 16s rrna gene sequence, an mlsa study by concatenating six genes, and ddh studies indicated that the strain d ... | 2010 | 20409659 |
| arsenite oxidation by pseudomonas arsenicoxydans immobilized on zeolite and its potential biotechnological application. | pseudomonas arsenicoxydans has been recently described as a new arsenite oxidizing bacterial species. arsenite detoxification activity by this species was determined by hplc/hg/aas. p. arsenicoxydans showed a high rate of as(iii) conversion, particularly when immobilized (it oxidizes 100 % of 500 μg arsenite present in the medium after 48 of incubation). arsenite oxidizing activity, mediated by a constitutive periplasmic enzyme, was determined following the transfer of reducing equivalents from ... | 2015 | 25673523 |
